2005 GMC Canyon Z71 SL 3.5L Poor Idle Quality, Hesitation, Cuts out VIN: 1GTDJ14615
P0068: Throttle Body Airflow Performance. Sounds like vacuum leak under cover for intake manifold. No smoke machine. Intermittent stall, rough idle and reduced power light comes on. Could be something but unfamiliar with this code.
